Answer:

$181.4

Step-by-step explanation:

Note,

purchase price = $90.70.

initial markup of 150% = $90.70 * (150% or 150/100) + $90.70 = $226.75 ($136.05 + $90.70). Hence, this became the intended sale price wanted by the store.
mark down (-) 80% = $226.75 * (80% or 80/100) = $181.4.

Therefore, the store applied a discount price of $181.4 to the set of golf clubs.

nadezda [96]

Answer:the cost of renting one movie is $1.5

the cost of renting one video game is $5.2

Step-by-step explanation:

Let x represent the cost of renting one movie.

Let y represent the cost of renting one video game. One month melissa rented 12 movies and 2 video games for a total of $29. This means that

12x + 2y = 29 - - - - - - -1

The next month she rented 3 movies and 5 video games for a total of 32$. This means that

3x + 5y = 32 - - - - - - - - 2

Multiplying equation 1 by 5 and equation 2 by 2, it becomes

60x + 10y = 145

6x + 10y = 64

Subtracting,

54x = 81

x = 81/54 = 1.5

Substituting x = 1.5 into equation 2, it becomes

3x + 5y = 32

3×2 + 5y = 32

5y = 32 - 6 = 26

y = 26/5 = 5.2

The sum of twice a number and another number is 24. The difference of twice the first number and the other number is 12. Which s

dem82 [27]

Answer:

The system that models the situation is:

$\left \{{{2x + y = 24} \atop {2x - y = 12}} \right.$

The solution is:

(9, 6)

Step-by-step explanation:

We must write the equations as indicated in the problem.

The sum of twice a number and another number is 24

a number: x

other number: y

Then

$2x + y = 24$

The difference of twice the first number and the other number is 12

first number: x

other number: y

Then:

$2x - y = 12$

The system that models the situation is:

$\left \{{{2x + y = 24} \atop {2x - y = 12}} \right.$

To solve the system we add both equations to find the value of x

$2x + y = 24\\\\2x - y = 12$

---------------------

$4x +0 = 36\\\\x=\frac{36}{4}\\\\x=9$

$2(9) +y = 24\\\\y=24-18\\\\y=6$

The solution is:

(9, 6)

A random sample of 133 people was taken from a very large population. Sixty-five of the people in the sample were females.The st

rjkz [21]

Answer: 0.0433

Step-by-step explanation:

Given: Sample size : n= 133

The number of females in sample = 65

Then the proportion of females : $P=\dfrac{65}{133}$

The formula to calculate the standard error of the proportion is given by :-

$S.E.=\sqrt{\dfrac{P(1-P)}{n}}$

$\Rightarrow S.E.=\sqrt{\dfrac{\dfrac{65}{133}(1-\dfrac{65}{133})}{133}}\\\\\Rightarrow\ \Rightarrow S.E.=0.0433444676341\approx0.0433$

Hence, the standard error of the proportion of females is 0.0433.
